Answer:
an = 39 +4(n -1)
Step-by-step explanation:
The formula for the general term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, the sequence has first term a1 = 39 and common difference d = 43-39 = 4. So, the general term is ...
an = 39 +4(n -1)
Is there some other part of this ?

Answer:
0.8%
Step-by-step explanation:
First, convert 7.5 m to cm.
There are 100 cm in one meter, so to convert this, multiply 7.5 by 100:
7.5(100)
= 750
So, there are 750 cm in 7.5 m.
To find the percent of 6 cm, divide 6 by 750, then multiply by 100:
(6/750) x 100
= 0.008 x 100
= 0.8
So, 6 cm as a percentage of 7.5 m is 0.8%
Answer:
12.21ft³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, square based pyramid.
Volume of square based pyramid is expressed as
V= a²(h/3)
Given data
Perimeter p = 7.3ft
Height h= 11.1ft
Since the shape has a square base let us solve for the length of each side
Perimeter of square p = a+a+a+a
p= 4a
7.3= 4a
a= 7.3/4
a= 1.83ft
Substituting our given data we have
Volume = 1.83²(11.1/3)
V= 3.3*3.7
V= 12.21ft³
